Skin Cancer Screening: When to See a Dermatologist
Meta Description: Skin cancer screening guide: when to see a dermatologist, how to perform skin self-exams, and ABCDE rule for suspicious moles.
Skin cancer is the most common cancer in the United States, with more cases diagnosed annually than breast, prostate, lung, and colon cancers combined. The good news? Most skin cancers are highly curable when caught early, and skin is visible—you can see changes yourself.
Screening for skin cancer involves regular self-examinations, professional skin exams, and knowing when to see a dermatologist. This guide explains what to look for and when to seek help.
In this guide, you'll learn:
- The three main types of skin cancer | How to perform skin self-examination | The ABCDE rule for suspicious moles | | When to see a dermatologist | Risk factors and prevention strategies

When in doubt, check it out:
Reality: Most "ugly duckling" moles are benign. But melanomas don't always look "typical." If a mole looks different from your others, have it checked.

SPF (Sun Protection Factor):
- SPF 15: Blocks 93% of UVB rays | SPF 30: Blocks 97% of | UVB rays | SPF 50: Blocks 98% of UVB rays
” Important: SPF measures protection against UVB rays (burning rays). Look for "broad-spectrum" for UVA protection (aging rays).

Frequently Asked Questions
Can I detect skin cancer myself?
Do all atypical moles need to be removed?
| | Not necessarily: | | | | Dermoscopy | Dermatologist examines magnified lesion | Monitoring | Some atypical lesions can be watched | Biopsy | Only if concerning features or changes |
Factors influencing decision:
- Patient preference (anxiety, worry) | - Lesion characteristics (how atypical, how changing) | - Patient risk factors (family/personal history, immunosuppression) | - Dermatologist experience and comfort level
Reality: Many atypical moles are benign. Dermoscopy helps determine which need biopsy and which can be monitored.
How do I tell if a spot is concerning?
Can I get skin cancer in areas not exposed to sun?
| | Yes, especially: | | | Location | Examples | Hidden areas | Between toes, under nails | Mucosal areas | Mouth, genitals | Rare cases | Buttocks, genital area |
Melanoma location: | |
- Ocular: In/around eye |
- Mucosal: Mouth, nose, genital areas |
- Subungual | Under nail |
- Plantar | Sole of foot |
” Important: Skin exam should include these hidden areas. Dermatologist examines all areas, including between toes, genital area, and scalp.
How quickly does skin cancer need to be removed?
| | Reality | "When in doubt, check it out": Don't delay evaluation of concerning spots | Sooner is better: Earlier treatment = smaller scar, better outcome | Delays can be fatal: Especially for melanoma |
Conclusion
Skin cancer screening—through self-examination and professional exams—is one of the most effective cancer screening strategies. Most skin cancers are visible and detectable early, especially when you know what to look for. The ABCDE rule helps distinguish benign moles from potentially dangerous melanoma.
Remember:
- Self-exam saves lives: Most skin cancers are visible and detectable by you
- The ABCDE rule: Asymmetry, Border, Color, Diameter, Evolving
- | "Ugly duckling" rule: Any mole different from your others deserves evaluation
- | Professional exams matter: Dermatologist sees what you can't; provides expertise | | Sun protection is critical: Cumulative UV exposure is #1 preventable risk factor | | Tanning beds are carcinogens: No safe level of use; complete avoidance recommended
- | | | Early detection is key: Thin melanomas have 95%+ survival; thicker melanomas are more dangerous
- | When in doubt, check it out: Suspicious spots deserve professional evaluation
Action plan:
- Monthly self-exams: Check your skin from head to toe, including hidden areas
- | Learn the ABCDE rule: Asymmetry, Border, Color, Diameter, Evolving
- | Document changes: Take photos of concerning areas; note size, location, characteristics
- | Get professional exams: Risk-appropriate frequency (annually to every few years)
- | | Protect your skin: SPF 30+ sunscreen daily, avoid tanning beds, seek shade
- | Know your risk factors: Fair skin, family history, extensive sun exposure, many moles
- | | When in doubt, check it out: Suspicious spots deserve dermatologist evaluation
Skin cancer screening is literally in your hands. Monthly self-examinations, regular dermatologist visits, and diligent sun protection can prevent most skin cancers or catch them early when they're most curable. Take 5 minutes once a month to examine your skin—it could save your life.
